JAMES A. "CROSBY AND JOHN J. PINK, OF CHICAGO, ILLINOIS, ASSIGNORS TO ,SIDNEY H. SELIG, TRUSTEE, OF CHICAGO, ILLINOIS.

MAo INE FOR TAKING-AND EXHIBITING PICTURES.

subject of the Dominion of Canada, and

JOHN JL'PINK, a citizen of theUnitedStates 5 of America, both residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Taking and Exhlbiting Pictures, of which the following is a specifica tion.

Our invention relates to certain new'anduseful improvements in machines for taking and exhibiting pictures; and its object is to produce a machine which shall avoid certain of theundesirable features now contained in machines of this general class. In these machines a seriesof pictures of animated ob-' jects are taken. upon a sensitized film, the

pictures following each other in rapid succession. These pictures are thenideveloped and reproduced upon a positive strip, known as the ribbo'n,-wvhich can be run through the machine and the pictures rojected u on a screenby means of asuitable ight, the efi ect being that a series of pictures are'produc'ed u on the sore n in which the movement When the pictures are to be takenu on the Iilm, the machine is entirely inclose in a suitable box, leavingnothing bgt the lens eX' osed. We have devised a machine of this'c ass in which the mechanism controlling the film and the, lighthas been. greatly improved, and to such end-our invention relates to certain novel featuresof construction, a description ficati0n and the essential features pointed of which Figure 1 1S afside view of the machine.

Fig. 16 is a view, partly in plan and partly in horizontal section, of the frame and lower magazine, the posts of the frame being cut away and the upperhalf of the magazinecut away in the line 16 16 of Fig. 1. Fig. 17 is a section in the line 17 17 of Fig. 1. Fig. 18is a fragmental view, of one of the magazine ribbon-guiding mechanism. Fig. 19 is an under plan view of the same, and Fig. 20

.,is a sectiohal view illustrating a modified form of shutter.

Referring to said drawings; 1 is the base, preferablyrectangular in form and bearing fourposts lfl 10 and 11 11, which support at their upper ends a bracket 12. Upon the base and bracket are removablysupported two arms 13 14, which support the magazines 2 and 2. These magazines are practically alike and will be described more fully later on in the courseof this specification. Upon the posts 10 is slidably mounted a frame 3, which carries the ribbon guiding and advancing mechanism the shutter, and shutter-operating mechanism. Thislframe is formed with perforated lugs 31, which en-Q circle the postslO and connect the frame 3 thereto. A lever 32, fulcrumed to. the base andipivoted to a lug 33 on the frame 3, is emloyed to shiftlthe position of the sliding ame upon the-posts, and a spring 34', interposed between the base and one of the lugs .31, serves'to ease the raising, of thefrarne. If desired, any or all of the ugs may be promachine.

chine the pictures on the ribbon are succesvided with some tension device for producing friction upon the posts. This is clearly shown at 31 in Fig. 4;.

'ihe ribbon, which is wound upon a spool in the magazine 2, is led through certain guiding devices, hereafter explained, to a spool in the magazine 2 to be wound upon said second spool alterpassmg through the In its progress through the mabon is then advanced to bring the succeeding pictures to the position previously occupied y the picture just in advance of it. During this interval the light passing through the lens is shut off, and the advancement of the pictures is not visible upon the screen. Likewise the film is not exposed during the shiftin of the film when. the machine is used in ta ing the pictures.

The mechanism for intermittently advancing the ribbon will now be described. The crank-shaft of the mechanism is seen at 5, Figs. 4 to 7, and is rotated by a crank 51. The shaft 5 is journaled in forwardly-extending lugs 35 on the frame 3 and carries a'gearwheel 52, which meshes with a pinion 53, fast upon a shaft 54, which is journaled in lugs 36 upon the frame. The shaft 54 bears a gear 56, which meshes with two pinions 57 and 57 upon shafts 58 and 589, The shafts 58 and 58 are journalednpon the frame'3 and bear cams 59 59*, (see Fig. 11,) which actuatea ribbon-advancing plate 6 to move it to and from the ribbon. The shaft 58 also bears a cam 519, which reciprocates the plate in a vertical direction. The intermittent advancement of the ribbon is effectedv by the plate 6 and the cams which actuate it. The

plate 6 is best seen in Figs. 11- to 13 and has four vertical working faces against which the cams 59 and 59'" bear in shifting the plate laterally that is, from front to back. It also has two horizontal working faces for the cam 510, and said cam engages these faces in -moving the plate up and down. ih e plate, it will be noticed, slides between two disks 61 62;, secured upon the two sides of the cams 59 and 59 and is guided laterally thereby. Vertical movement and movement to and from the ribbon is entirely controlled by the" cams 59, 59 ,-and 510. The working faces of the plate, which. are engaged, by the cam 510,

are upon horizontal bars 63, which are separated from the plate by small blocks, as clearly shown in Fig. 12. Upon the front edge of the plate 6 is a plate 64, which bears four pin's 65,.which engage with the perforation in the ribbon A.

The. cams 59, 59 and 510 are so constructed and timed that in a cycle of opera- 'therefrom when the ribbon 1 tion a quarter-revolution draws the plate down, advancing the ribbon, and the remaining three-quarters of the revolution retracts the plate fromthe 11l)l)0l1, returns it to its uppermost position, and shifts it back to the ribbon, this being the position from which it started. In a cycle of operation the ribbon is thus exposed during three-fourths of the period and shifted during the remaining onefourth of the period. Pictures which are exposed to viewfor a less period than this are not so clear and distinct, and when less time is used ina cycle of operation to shift the picture there is much danger of the ribbon being torn by the advancing mechanism. in Fig. 7 the plate 6 is shown at its uppermost position with the pins in engagement with the perforations in tho ribbon. A quarter revolution of the shafts 58 58 will draw the plate down in a straight line, consequently advancing the film. Another quarter-revolution will bring the plate into the position shown in Fig. 11. During the completion of the revolution the plate will be raised to its uppermost position and then shifted back, bringing the pins into engagement with the perforations in the ribbon. it should be noticed that the cams are so shaped that when.

the plate ismoving up or down no lateral movement takes place and that when moved laterally no vertical movement is effected.

The plate thus follows a perfectly rectangular-coursein its movement, drawing the ribbon down in a perfectly straight line.

The ribbon as it comes from the magazine a roller 71. The sprocket ismounted upon a spindle journaled in brackets 37 of the frame if, and said spindle bears a gear-wheel 7, connected by a train of'gears 72 73 74- 75 76 7 with the gear 53, heretofore referred to. The sprocket 7 is geared to rotate at a speed 2 passes between a sprocket 7 (see Fig. 7) and which will feed the ribbon to the advancing mechanism as fast as said mechanism advances it along. The roller 71 is mounted upon a frame 78, spring-pressed toward the sprocket and capable of being separated threaded through the machine. A spring 79 engages a lug 78 on one side of the center of the pivot v of said frame and'holds the roller in contact with the ribbon or sprocket. When the roller is swung a certain distance away from the sprocket, the spring actslto hold it back after the manner of the ordinary holdback- .through the machine and afterward closed to direct the course of the ribbon in its passage by the exp'osureeopemng m the plate 4.

as shown I The gate 43 supports a pair of friction-shoes 44, .which press uponthe -'ribbon near its edges and apply friction thereto, so to steady its movement through this portion of the machine and prevent-any vibration or other movement thereof while in a position of rest and exposure.

Asshown, the pins 65 extend through slots in the plate 4 and engage the ribbon. The shoes 44 are also slotted to permit the ends of the pins to-move freely therein. The shoes are mounted upon the gate 43 by means of pins 45 47, which pins are secured to the shoes and pass through perforations in the gate 43. (See Figs. 9 and 11,) A spring 47 is secured upon the outer face of the gate 43 and is screwed to a cross-bar 46, (see Figs. 8 and 1],) which cross-bar in turn is secured to the shoes 44 by the pins 47. The ins 47" are located approximately midway )etwcen the ends of the shoes, so that pressure upon them by the spring 47 will be distributed equally along their entire bearing-surface. The shoes are of considerable length and extend past the light-opening and beyond the ribbon-advancingjmechanism, thus maintaining the ribbon in a perfectly flat condition as it passes the light-opening and the advancing mechanism. The tension of this spring is regulated by a thumb-nut 48, so that the desired amount of friction upon theribbon can i be had by adj'ustingthc thumb-nut '48.

. thereto.

Rollers 49 are ournaled upon the ends of the gate 43, and the ribbon passes over these rollers in entering and leaving-the guidingchannel between the gate 43 and plate 4. The gate is formed with an opening in line with the opening in the plate 4, and the light from the lamp passes through these openings and through the ribbon and to the screen. In front of the plate 4 is a diaphragm 4 which is supported upon the posts 10. The opening in this diaphragm is approximately the same size as the-pictures upon the ribbon and is in line with the lens and directly in front of the opening in the plate 4. The picture is framed by raising or lowering the sliding frame 3 to bring the picture in front of the opening in the diaphra m.

We have provided. a ligT1t screen400, hinged to the door and held in an open or shut position by a spring. the lamps which are used in connection with devices of this class is very intense at this point, and it often happens that when the ribbon stops for some cause the light sets fire By swinging the shield down upon the opening any. danger from fire is thus avoided.

Below the gate 43 is a second sprocket 7 and roller 701,. between which the ribbbn passesafter it leaves the lower roller 49. The

, sprocket 700 is journaled in brackets 33 and 33- and its spindle bears a gear 702 in mesh with a gear 703, which meshes with the gear The light from 52. The sprocket 700 is geared to rotate at the same speed as the sprocket 7. The roller 701 is journaled upon an bears a spindle 708, journaled. in the lugs 33 33'. The roller and spindle are eccentrically disposed with respect to eachother, and the roller is held incontact with the ribbon by a fast upon the spin e 7 08. When threading the machine, the roller 701 is swung away spring 705. This disposes of the ribbon-advancing mechanism, scribe themechanism for intermittently exposing the ribbon and shutting off the light.

111 front of the diaphragm is a rotatable 3 of. the machine. This shutter bears a miter-gear '81, which meshes with a mitergear 82, (see Fig. 4,) fast upon the spindle 74 of the pinion 74 of the train running from the cut away at certain places for the passage of .the' light, and the parts of the shell which remain formblades which cut oil the passage of the light. The shutter is formed with two blades 83 and two blades 84, which extend between the two heads 85 of the shutter. The two blades 83 cut oil the light to the screen when they pass the diaphragm-opening, and their assage by said openingris timed totake p ace simultaneously with the advancement of theribbon'. When the ribbon comes to a position of rest, the blades 83 again pass through. Much diliiculty has been encountered in machines of this kind, because of the flickering of the picture upon the screen. We have found that by passing a yery small blade in front of the ribbon while the icture is exposed this diiiiculty is practical y avoided. The blades 83 are provided for this purpose.- The lens is shown at and with, machines of this class.

I In-Fig. 20 we have shown a slightly-modified form of shutter. The blades are here mounted "upon a chain and pass up and down before the ribbon.

useful when it is desired to use a short-focus lens, in which case thelens can be brought much nearer the ribbon.

The ribbon is wound upon a spool 21 in the magazine 2, and this spool is 'removably clamped upon a spindle 22. The spindle is journaled in the arm 14 and bears upon its outer end a pinion 28, which with a crank for its rotation. This mechanism' is usedv for rewmding the ribbon after it *7 has been run through" the machine. The

all. 4.:

17. The arm bears a slotted plate 18, through which the screw pro ects, and the angular position of the magazine can be fixed *byturning it to the proper position and then bon in issuing from the magazine passes between the rollers 26 and 27. The wall of the magazine is cut away at 28 (see Fig. 3) to permit the ribbon to be passed sidewisc into This obviates the necessity of threading the ribbon out through the opening in the periphery of the magazine. The door of the magazine is shown at 29 and is hinged thereto in any suitable manner. W hen it is closed and. the gate 25 is swung into place, the slot28 is completely closed. The magazineZZ and its spool are like the ones just described, except thatthe s indlc bears a pulley 200, which is connecte by a belt 201 to a driving-pulley 511, fast upon the crank-shaft 5. This belt is preferably in the form of a coiled spring, so as to allow of the vertical adjustment of the frame 3. itis desirable that the driving connection between the pulley 200 and the spool be'in the form of some sort of friction appliance, so that the spool may not rotate any faster than is necessary to wind up the ribbon, regardless of the speed at which the rest of themechanism is driven. It will be understood that as the ribbon becomes wound upon the spool the 5 diameter of the roll becomes greater, and were the spool to rotate at the same uniform speed the ribbon would become torn off. To avoid this possibility, the pulley 200 is loose upon the spindle and is held in frictional contact with a disk 203, which is fast 11' on the shaft, by a spring 204.

The tension of the spring is regulated by a thumb-screw 205, which is provided with a spring-pointer 206, which moves around with t e thumb-screw as it is turned to vary .the

tension. The ointer passes infront of a dial 207, whichis formed with radial notches into which the pointer snaps as it asses, so that the position of the pointer can e told in the dark as well as in the light. Starting withthe empty spool and the tension adjustedproperly, the operator can decrease the amount of tension as the spool fills up, and

consequently decrease the speed thereof. The

end thrust of the spindle is "taken up by a ball-bearing 209, as shown in Fig. 16.

The operation of the machine in exhibiting pictures is as follows: The ribbon, which has previously been wound upon the upper spool, is threaded through the machine and onto the lower spool.

atone? The frame 3 is then adjusted to frame the picture, the light from the lamp projecting the picture upon the screen. The crank 51 is then rotated, and rotation of the cam-shafts 58 and 5S" and cams 50, 50, and 500 is eil'ected through the gearing. The ribbon-advancing plate (5 is consequently reciprocated and moved into and out of en gagement with the ribbon by said cams, each downward movement of the plate advancing the ribbon one step, and the continued reciprocation of said plate brings the pictures in succession to a posilion in front of the d iaphragm-Zopcning. Simultaneously with the advancement of the ribbon the blades 83 of the shutter pass said opening and shut oil the light. By the time the ribbon comes to a po'sition of rest thcblades have passed by the opening, and the. light is again permitted to pass through, projecting the picture upon the screen. ViThilc the picture is thus exposed the narrow blades 84 pass through the rays of light, making the picture a trille, dimmer, but apparently reducing the flickering to a marked degree. The sprocket 7 is "rotated by its train of gears and feeds the ribbon to the advancing mechanism, and the sprocket 700 is likewise rotated by its train of gears to carry the ribbon away as fast as it is fed for ward. After passing the sprocket 700 it entors the lower magazine, when it is wound upon the spool. When the entire ribbon has passed through the machine, it may be rewound upon the upper spool without assing back through the machine. This (lime by loosening the thumb-screws 17, turning the magazines until the gates are opposite each other, opening thegates, attaching the ribbon upon the upper spool, and turning the crank.

Particular attention is called to the fact that the ribbon-advancing plate is supported and guided entirely by the cams which operatethe plate. This obviates the necessity of providing other guiding or supporting devices for the plate, thereby reducing the friction and number of parts to a minimum.

We realize that considerable variation is possible-in the details of this construction without departing from the spirit of the invention, and we therefore do not intend to limit ourselves to the specific form herein shown and described. I
